"Is it even worth paying money for a finished game?"

In all stores, when you buy a game, you get a receipt. And then, if you don't like it, you can return the product without wasting money. :)
And if there are errors and bugs, etc., there are always patches (they are released for almost all games, IMHO):D And if you don't like the monsters, you can wait for something like: Heroes 6.5 :D There are always ideas somewhere.:rolleyes:

The phoenix description is in place. As I understand it, when the phoenix is reborn, there will be an additional effect, similar to that flash of light that was in the screenshot. Quite interesting.
